Answer:
Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly colored gas.
Answer: 0,4278g of F and 0,4191g of Fe
Explanation: it's possible to calculate the mass of each element by multiplying the percentage (decimal) of the element by the mass of the compound.
For Fluorine (F)
0,847g * 0,5051 = 0,4278g of F
For iron (Fe)
0,847 * 0,4949 = 0,4191g of Fe
This is determined because even when the compound is decomposed, due to conservative law of mass, the decomposition process do not affect the amount of matter, so the mass of the elements remain even if they are separated from the original molecule.
At the end, the sum of the elements masses should be the total mass of the compound.
Answer:
it opposes motion. the object would continue to slide forever if not stopped by another object.
Answer:
The mass of the forest comes from carbon and carbon is retrieved from carbon-dioxide that trees used during the process of photosynthesis. In the process of photosynthesis, carbon-dioxide is utilised from the atmosphere by trees and release oxygen and ATP.
When the forest burns the mass again releases to atmosphere in the form of carbon which causes air pollution and increases carbon content in the atmosphere.
